Source changes:
---------------
- Various ZN related updates [smf, R.Belmont]:
  * Several games now display more, for example primrag2 plays the intro movie.
- i386 CPU core (used by the SPI driver) [Ville Linde].
- ST-V Improvements. GFX in colmns97 / sassisu / ejihon are improved [Mariusz Wojcieszek]:
- CHDMan CHDCD creation fix [R. Belmont].
- Improved timing of several 68k instructions. These changes could do with being verified on a real 68k. [Sebastien VOLPE]:
	m68kcpu.h, m68kcpu.c:
	---------------------
	A) scc (68000 only): CYC_SCC_R_FALSE was defined, not used, and misnamed as the extra 2 cycles happens when CC is true: now used and renamed to CYC_SCC_R_TRUE.
	m68kmake.c:
	-----------
	B) add/adda/and/or/sub/suba (68000 only): the 'extra 2 cycles' cases were not handled correctly: corrected to be effective on .l only, and also on register direct (previously, all sizes were affected, and only in immediate mode).
	C) jmp d(An,Xn) / pea (An) (68000/68010): tables corrected.
	D) movem (68000/68010): generated basecount were incorrect in many cases, so I added a dedicated table.
	m68k_in.c:
	----------
	E) movem.l d(PC),reglist / movem.l d(PC,Xn),reglist (68000/68010): changed basecount.
	F) asr/asl/lsr/lsl/ror/rol/roxr/roxl (68000/68010): added '+2n' cycles where missing, as the shift/rotate memory is the only case where '+2n' does not apply, and is treated in a specific opcode handler.
